Once you receive the Notice of Action 2, the Embassy in charge of your file (in my case, the Embassy of Paris) sends you an email with the next steps to follow before the official interview (in my case, in Paris).You have to follow those instructions very carefully. The documents you need will depend on your case. It is possible that you have additional documents to bring with you. The list I am about to write is only my personal example. The email of the Embassy has the priority here on the blog. Steps are all developed in the email you receive.

One original or a certified copy of the birth certificate (must state the date and place of birth and the names of both parents. The certificate must also indicate if it is an extract from official records)

Recent Background Check ( The ideal is one of less than three months)

An original/signed letter from the U.S. citizen stating that the Petitioner and the Beneficiary remain legally free to marry and continue to intend to marry each other within 90 days after the Beneficiary’s admission into the United States.

I recommend that you bring a copy of the package as an agent totally has the right to ask for any evidence at any moment (this is why it is important to make photocopies of everything and to bring the original papers with you too). Also because you will need to have your I-135 form with you (explanation about what is an I-135 form in the next article)

Once all the papers are gathered, and only at that moment, you need to fill the DS-2001 which states that you are ready for the future interview, sign and date it. The address where the DS-2001 has to be shipped is written on the top of the email. Also, the documents that I mentioned before are to be kept aside for the future interview, only the DS-2001 has to be sent to the Embassy. You will receive instructions about the interview and the medical appointment (as well as how to pay them) once the DS-2001 is signed and that the Embassy receives it.

UPDATE (2017): I TALKED TO FUTURE EXPATS AND THEY TOLD ME THAT THERE WAS NOT A DS-2001 MENTIONED ANYMORE. THINGS HAVE CHANGED IN BETWEEN SO YOU MUST FOLLOW THE INSTRUCTIONS GIVEN BY THE EMBASSY TO THE LETTER.

NOTE : The price of the envelope which will contain your visa + passport, if everything goes well, is included in the total price.
